Experiments were conducted to study axial liquid dispersion coefficient in slurry bubble column of 0.15 m inside diameter and 1.6 m height using perforated plate gas distributor of 54 holes of a size equal to 1 mm diameter and with a 0.24 free area of holes to the cross sectional area of the column. The three phase system consists of air, water and PVC used as the solid phase. The effect of solid loading (0, 30 and 60 kg/m3) and solid diameter (0.7, 1.5 and 3 mm) on the axial liquid dispersion coefficient at different axial location (25, 50 and 75 cm) and superficial gas velocity covered homogeneous-heterogeneous flow regime (1-10 cm/s) were studied in the present work. The results show that the axial liquid dispersion coefficient increases with increasing superficial gas velocity, axial distance, solid concentration and an inverse relationship with particles diameter.
I was invited to deliver a research paper on orphan care at the Center for Psychological and Educational Research. So I sought help from God Almighty and began writing a research in which I explained the meaning of the orphan, his condition, and the Holy Qur’an’s care for him.

Although modern and contemporary Islamic thought has established its intellectual foundations on the fundamentals of intellectual thought that are at the core of its Islamic intellectual system, at the same time many of its intellectual products have been a response In spite of the fact that this Islamic intellectual response stands out from Western modernity as a negation or a positive attitude. The Islamic intellectual response differed in determining its position on Western modernity, depending on the nature of the historical stage that was The Islamic nation, as well as the nature of the challenge posed by Western civilization to other nations and other c

These attempts come in harmony with the spirit of the times in seeking exoticism, surprise and splendor as a means of renewal. modern Art . Therefore, the research was divided into four axes, the first of which included the research problem, its importance and its aim, which is to attempt to uncover the metaphorical metaphorical relational mechanism in modern sculpture. The second axis included the theoretical framework. The third axis included the research procedures of determin
